| 摘 要： | 介绍测量接收机与矢量网络分析仪测量衰减的原理，并对不确定度来源进行了分析。分别对低反射系数下，不同衰减量进行不确定度评定，表明衰减量在（10～60）dB范围内，两种标准测量不确定度相当；另外，采用两种测量标准对较大输入反射系数模值、不同相位下的阻抗调配器级联20dB固定衰减器作为被测件进行测试，最大偏差达到±0.31dB，矢量网络分析仪的测量不确定度（0.18dB），明显小于接收机测量不确定度（0.59dB）。

| Abstract: | This paper introduces the principle of measurement attenuation between measurement receiver and vector network analyzer,and analyzes the source of uncertainty.The uncertainty of different attenuation is evaluated under the low reflection coefficient,which indicates that the attenuation is in the range of 10dB~60dB,and the two standard measurement uncertainties are equivalent.In addition,the two input measurement modes are used for the larger input reflection coefficient and different phases.A Tuner Cascading 20dB fixed attenuators are tested as the device under test.The maximum deviation is ±0.31dB.The measurement uncertainty of the vector network analyzer(0.18dB) is significantly smaller than the measurement receiver measurement uncertainty(0.59dB). |
